D256 Austenitic Manganese Hardfacing

Material overview

D256 Austenitic Manganese Hardfacing is included in the Hardfacing & Wear Welding Consumables catalog. 13Mn austenitic deposit that work-hardens under impact, for high-manganese steel repair. Key characteristics for evaluation include Tough and initially soft, surface work-hardens to HRC 50+ under impact, and resists cracking. Typical applications include Crusher hammers and jaws, excavator bucket teeth, railway crossings, and mill liners. The dataset currently includes 7 property records covering chemical composition and mechanical properties. Associated standards include A5.13 and A5.21, and product form records cover Covered Electrode and Flux-Cored Wire. Final chemistry, mechanical properties, heat treatment, dimensions, inspection, and documentation must be confirmed against the applicable specification and mill certificate.
